, PREssUnn-ornBABLE VALVE.

Application filed April 9,

designed to limit the fluid in a chamberto a' certain pressure, it is partlcularly designed for use in bottling machines on devices of the type set forth anddesc'ribed in my pend ing application for United States Letters Patent numbered 680,624.

A further object is' to provide a pressilre operable valve which may be quickly taken apart for the purpose of cleaning', repairing I or replacing any-of the parts of which is composed and to provide a combination "and arrangement of parts which may bequickly" reassembled and accurately adjusted to oper ate at a certain desiredpressure.

, The above objects are accomplished and' other ends are attain'ed by the] novel construction, combination and arrangement of parts hereinafter described. and illustrated in the accompanying drawing, wherein I have shown a preferred form of the'invention, it being understood'that the invention may be adapted in various ways 'to'various uses and that changes and modifications may be made or substitutions resorted to which come within the spirit of thc invention as set forth in the appended claims.

In-the drawings ,like numerals ofrefer ence are used to denote'like .p'artsas the same a may appear in any of the severa-lviews and in which Figure 1 is a; central, erticahsectional view of a valve constructed in"accorda'nce with this invention,

Figure 2 is a plan view 'of 'a valve seat employed in ca rrying out the invention.

Figure 3 ,is aside elevational view of' a valve constructed in accordancefwith this invention c Figure {is a plan view of one ofthe weights which may be employed toregulate the device to operate at a certain pressure."

A valve constructed in accordance with this invention comprlses" a tube 5-h'a v1ng a cup 01' valve seat 6 secured to the upperend 7 thereof; The cup or valve seat 6 comprises 1924. Serial no; 705,258.

positioned in said-bore? with the upper end thereof flush with the upper face of the disk and the-said tubeis'secured in said bore 7 by brazing, soldering or any suitable means.

[PATENT 0 m,

a circular disk 6 having an axially arranged bore 7 which is adapt'ed to snugly receive the upperend of the tube 5. The tube 5 is The disk? is provided at the outer edge 1 thereof with a circumferentially extending up-standin-g flangefi". The'flangefi is pro vided with a concentrically arranged flange 8 which is formed thereonijin spaced relation to said bore 7 and in spaced relation to the flange 6 The flange 8 is of triangularcross section and projects upwardly from the up pjer'face of'the disk 6%. Thenumeral 9 de notes a flat, cylindrical weight 'which' is a'daptedto be loosely received in the cup formed by the flange 6", and is adapted to seat on the flange. 8 to form a fluid tight. joint; The'disk 9 is provided with acoaxially arranged downwardly projecting'pin.

10 which is positioned in the upper end of the bore in the pipe 5 to assist in maintaining 1 the disk 9in' acentral position in the cup '6. The disk 9 is likewise provided on the upper face thereof with an upwardly projecting,

coaxially arranged-pin 10, the purpose 0 which will be hereinafter described; I

The numeral 11 denotes a'collar whichis in the form ofa disk'l'iaving an axially arranged bore and which is slidably mounted on the pipe 5 ata point below the cup 6.

The collar'll is" secured in a fixed'position; on the pipe 5 by means of a set screw 12- which is operatively threaded inathreaded bore 13 which projects radially into the collar11,;wherebythe collar 11 may be s elec tively'moved on the pipe 5 andsecured vin a fixed position'by' operating the screw 12.

vThecollar llisprovided on one side there of with a radially directed threaded bore 14. An arm 16 is secured to the collar 11 by means off-a bolt '15 which is positioned through a suitable bore in the lower'end of the arm 16 and is threaded into the'bore 14. The arm'lfi projects upwardly'to a point above theweight 9, and the upper end thereof is bent at a right angle to form a horizontal portion 16 which projects di rectly overtlie center ofthe'weight 9. The

horizontal portion 16* -is provided at a point 7 in axial alinementwith the bore of thepipe 5, with the threaded bore 17 in l which is ro-' 4 ,vided with an axial'bore 20 and is provided mounted a screw '18. The-screw 18 is i position in the cup 6. If desired, the'devic'e mayabe used withoutthespring 21 and may the bore 2d to regulate the valve at the-lower end'thereot with a cup 19. The

stem 10 is entered in the bore ZOand a 001i spring 21 is mounted on the stem 1O with the upper end thereofreceived -in*the cup 19 whereby the screw lSn'iay. vbe .,op.-

The nun'ieral 22 denotes a lock washer which is em-ployedtosecure the screw-18 in a fixed position relativeto the arm16. The numeral 23 denotes a weight which-is in 'thetorm of a disk and which is provided Wltllfi centrally positioned aperturefid; One I or more or, the weights 23'may ,be placed on;

TY'ltllOtlt these weights as-shown 1n Figure'l. Inasmuch as the screw vl8 may be-.-'operated rtocompress; the spring; 21 to regulate the pressure at which the valvewill operate, the idevicemay also: beregulated by operatingthe screw 12 and slidingthecollar V downwardly on the. pipe 5,Jwhereupon the screw: 12Fma-y be :set to holdthe collar .11 in fixed position.

In use, thelower end of bore of rthe tube 5 in; communication with sa1d chamber. Thecollar;13 is regulated on thetube 5 to compress thespringaflli The;

screw-18 is then 'operatedi-to adjust the compression of the springs-=21 tocmoreaccurately regulate the device to' operate at thea desired pressure.

It will be 'seenthat the pin 10 being.
